WHAT: It would take a mighty big margarita to cool us off enough for three hours in the August heat. Luckily, the drink slingers at Wall Street Plaza's Margarita Fest will be able to provide a bottomless cup. Enjoy unlimited samples of more than 20 different drinks throughout the plaza and the adjoining Heritage Square this Saturday, while live reggae from Horizen and 506 Crew sets the scene. VIP drinkers needn't worry about the heat, with access to the Tequila Terrace at Monkey Bar, free appetizers and more.
